Value at Risk historical simulation
Hi Has someone got a package/script at hand to do a historical simulation to calculate the Value at Risk? If your not sure what Historical Simulation is: In simple terms, Historical Simulation (HS) is just taking sample percentiles over a moving sample. Suppose we want to use HS to predict a portfolio's Value-at-Risk at a confidence level of 99 percen...

R function for estimating historical-VaR
Hi everyone!! I am new in R and I want to create a simple R function for estimating historical-VaR. In y_IBM returns, there are 2300 observations. For evaluation I take the next 2000 observations, then I abandon the latest 300 observations. Firstly, I use the window which has the fix length and contains the observations from 1 to 2000 to estimate the VaR. At first I take 2000 obs. and...

calibration of Garch models to historical data
I have done the usual estimation of GARCH models, applied to my historical dataset (commodities futures) with a maximum likelihood function and selected the best model on the basis of information criteria such as Akaike and Bayes. Can somebody explain me please the calibration scheme for a GARCH model? I was not able to find a paper, dealing with exactly this algor...

Constant (= wrong) historical quotes via get.hist.quote() from yahoo.finance
Dear expeRts, I would like to download a time series of historical data from the ticker with symbol "ROG.VX". Interestingly, I obtain constant values (138.3 for each day in the chosen period) although the yahoo.finance website tells me that the time series is not at all constant. What's wrong? Cheers, Marius require(tseries) hq <- get.hist...

Using Ruby on Rails to Create Historical Blog
Hi, everybody. For a long time I''ve been interested in putting together a blog-like Web site where I write "posts" on historical events and then the posts are automatically ordered on the main page by the date of the events that they describe. I first had the idea because I thought it would be really easy to just back-date the posts to historical dates and have them automatically arranged for me. Turns out this won&...

Zero listeners on icecast stats
...steners. Our setup is this: We have a listening mount point for people - that fall back to a live streaming from a cellular phone - that fall back to a live streaming from a base station (a pc), that fall back to a 24/7 archive streaming. No matter what the sound source is (cellular phone, PC or historical archive 24/7, our listening mount point always show zero listeners. But we have listeners there, and they are listening our stream, and everything works fine. Any hint about this? Server is icecast 2. we stream using mixxx from an Imac, darkice from PC and liquidsoap for our mp3 archive, stre...

How to choose a button and scrape the website data
...e XML to get the dataset. However, some of the website doesn't give a explicit address of the downloaded tables. To be more specific, for example, I'm interested in the website http://ets.aeso.ca/ The data we are scraping is the "Pool Weekly Summary" under the category of "Historical". However, after clicking "historical" and choose the "Pool Weekly Summary" item on the website, the address is always http://ets.aeso.ca/ and doesn't change. In this case, I guess I need to tell R first click the "historical" button then choose the it...
